gpsfake 1 12 Feb 2005 gpsfake test harness for gpsd, simulating a GPS gpsfake -h -c interval -n -s speed logfile gpsfake is a test harness for gpsd and its clients. It opens a pty (pseudo-TTY), launches a gpsd instance that thinks the slave side of the pty is its GPS device, and repeatedly feeds the contents of a test logfile through the master side to the GPS. Because of the baud-rate hunting logic, the first sentence in the file will not be the first presented to the sentence parser. The -c option sets the delay between sentences in seconds The -n option suppresses launch of the daemon. Instead, gpsfake will tell you the name of the slave pty so you can launch in instance that reads it. The -s option sets the baud rate. Note, this will only work if the chipset accepts a speed-change command (SiRF-II supports this feature). The -h option makes gpsfake print a usage message and exit. The argument must be the name of a file containing the text of NMEA sentences to be cycled at the device. gpsd1 libgps3 libgpsd3 gpsprobe1 gpsprof1 gnuplot1 Eric S. Raymond esr@thyrsus.com.
